The #Omicron variant spread between two fully vaccinated travellers across the hallway of a #HongKong quarantine hotel, underscoring why the highly mutated #coronavirus strain is unnerving health authorities.
Closed-circuit television camera footage showed neither person left their room nor had any contact, leaving airborne transmission when respective doors were opened for food collection or #Covid-19 testing the most probable mode of spread, researchers at the University of Hong Kong said in a study published last Friday (Dec 3) in the journal Emerging Infectious Diseases.
Omicron, with an "unprecedented" number of mutations in its spike protein, has raised concern that it could evade vaccine-induced protection, worsen a surge in Covid-19 cases and frustrate efforts to reopen economies.
